Cosmanthus fimbriatus 1867

14 fl. crossed & produced 9 pods (ie 64 per cent) with average of 2.0 seed with max. of 3

18 self flowers produced only 4 pods (ie 22 per cent) containing average of 3.2 with max. of 4 & seeds certainly finer; so impossible to say which union most fertile.

(Season evidently bad.)
